The Wikipedia page at http://en.wikipedia.org/wiki/Laws_of_cricket says: The Marylebone Cricket Club is the framer of the Laws of Cricket, the rules governing play of the game. . The Laws retain the Imperial units as they were originally specified, but now also include metric conversions. The metric conversions are interesting as they not only convert the old measures but also round them sensibly. For example, the length of a cricket pitch in the old rules was 22 yards. Assuming that these are the metric yards of exactly 914.4 millimetres, then a direct conversion would give a pitch length of exactly 20.1168 metres. However, it seems that this has been sensibly rounded, in the Laws of Cricket to 20 metres. I quote again from the wikipedia article: Law 7: The pitch. The pitch is a rectangular area of the ground 22 yards (20 m) long and 10 ft (3.0 m) wide.

Also when teaching about conversions I've seen questions asking for answers using 'either metric or imperial'. Martin - in the past I've directed you to websites showing such questions and confirmation about being curriculum based. _____ From: [email protected] To: [email protected]; [email protected] Subject: RE: [USMA:45750] RE: Mathematics improvement due to metrication Date: Mon, 7 Sep 2009 20:15:46 +0100 The UK curriculum only teaches children how to convert between imperial and metric units (approximate conversions only). It does not teach children how to manipulate imperial units. For example, no child in the UK is taught how to solve the problem "Find the average of 3lbs 6oz, 4lbs 2oz, 6lbs 15oz". They are however taught how to solve the problem "Find the average of 1.53kg, 1.88kg and 3.15kg". They might even be taught how to use the "Average" button on their calculators. _____ From: [email protected] [mailto:[email protected]] On Behalf Of Stephen Humphreys Sent: 06 September 2009 22:37 To: U.S. Metric Association Subject: [USMA:45750] RE: Mathematics improvement due to metrication I was at school in the 80's and at that time they had dropped imperial from the curriculum completely (aside from Teacher/kids talking casually using imperial terms, of course!) Shortly after they made imperial part of the curriculum including conversions to and from, usage, etc. In science classes the units were and still are only metric though. _____ From: [email protected] To: [email protected] Subject: [USMA:45745] Mathematics improvement due to metrication Date: Sun, 6 Sep 2009 14:58:23 +1000 Dear All, The Telegraph at http://www.telegraph.co.uk/education/6138456/Maths-standards-no-better-than- mid-70s.html and the Daily Mail at http://www.dailymail.co.uk/news/article-1211345/Maths-skills-standing-thirty -years-GCSE-grades-soaring.html have both reported that metrication has helped students in the UK with decimals knowledge. Here is the quote from The Telegraph: It found secondary pupils were much more familiar with decimals than they were 30 years ago. Researchers put this down to "cultural changes" including metrication and the increased use of calculators and computers.
